+.It Va ListenAddress Li = Ar address Op Ar port
+If your computer has more than one IPv4 or IPv6 address,
+.Nm tinc
+will by default listen on all of them for incoming connections.
+This option can be used to restrict which addresses tinc listens on.
+Multiple
+.Va ListenAddress
+variables may be specified,
+in which case listening sockets for each specified address are made.
+.Pp
+If no
+.Ar port
+is specified, the socket will listen on the port specified by the
+.Va Port
+option, or to port 655 if neither is given.
+To only listen on a specific port but not on a specific address, use
+.Li *
+for the
+.Ar address .
+.It Va LocalDiscovery Li = yes | no Pq no
+When enabled,
+.Nm tinc
+will try to detect peers that are on the same local network.
+This will allow direct communication using LAN addresses, even if both peers are behind a NAT
+and they only ConnectTo a third node outside the NAT,
+which normally would prevent the peers from learning each other's LAN address.
+.Pp
+Currently, local discovery is implemented by sending broadcast packets to the LAN during path MTU discovery.
+This feature may not work in all possible situations.
+.It Va LocalDiscoveryAddress Li = Ar address
+If this variable is specified, local discovery packets are sent to the given
+.Ar address .
